RNF14FAD97K6 Equivalent & Substitute Parts

Part Overview

The RNF14FAD97K6 is a 97.6 kOhms ±1% metal film axial through-hole resistor rated at 0.25W (1/4W) manufactured by Stackpole Electronics Inc. This component features flame retardant coating and safety-grade construction, designed for applications requiring precision resistance values in compact form factors. The part is currently active in production with full RoHS3 compliance. Substitute parts may be required due to inventory constraints, application-specific power rating upgrades, or design optimization for improved thermal performance and temperature stability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FAD97K6 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 97.6 kOhms (exact match required)
• Tolerance: ±1% (precision grade must be maintained)
• Composition: Metal Film (electrical performance characteristics)
• Package type: Axial (mechanical and PCB compatibility)
• Number of terminations: 2 (electrical connectivity)

Allowable Variation Parameters:

• Power rating: May be equal or higher (0.25W or greater)
• Temperature coefficient: May be equal or lower in absolute value (±100ppm/°C or better)
• Operating temperature range: May be equal or wider
• Physical dimensions: Minor variations acceptable within axial package constraints
• Packaging format: Different tape/box configurations acceptable

The CMF5597K600FHEB qualifies as a direct substitute because it maintains all mandatory parameters while offering enhanced specifications in power rating (0.5W vs 0.25W), temperature coefficient (±50ppm/°C vs ±100ppm/°C), and maximum operating temperature (175°C vs 155°C).

Parameter Comparison

Engineering Selection Recommendations

The CMF5597K600FHEB represents a direct functional equivalent to the RNF14FAD97K6 with enhanced performance characteristics. Both components maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent applications.

Selection between these parts should be based on application requirements:

• RNF14FAD97K6: Select when the 0.25W power rating is sufficient and component size is not a constraint. Stackpole Electronics Inc sourcing preferred.

• CMF5597K600FHEB: Select when improved thermal performance is required, higher power dissipation capability is needed, or superior temperature stability (±50ppm/°C) is specified. The Vishay Dale CMF series offers additional moisture resistance and extended operating temperature range to 175°C.

Both parts are active products with established supply chains and full compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can CMF5597K600FHEB replace RNF14FAD97K6 in existing designs?

A: Yes. The CMF5597K600FHEB is electrically and mechanically compatible. The resistance value, tolerance, and axial package type are identical. The higher power rating (0.5W vs 0.25W) and improved temperature coefficient (±50ppm/°C vs ±100ppm/°C) provide enhanced performance margins without affecting circuit functionality.

Q: Are there physical size differences between these parts?

A: Minor dimensional variations exist. The CMF5597K600FHEB is slightly smaller (0.090" Dia x 0.240" L vs 0.093" Dia x 0.250" L). Both maintain standard axial package geometry and are compatible with equivalent PCB footprints and through-hole spacing.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both RNF14FAD97K6 and CMF5597K600FHEB are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and safety requirements.

Q: What is the difference in packaging format?

A: RNF14FAD97K6 is supplied in Tape & Box (TB) format, while CMF5597K600FHEB is supplied in Cut Tape (CT) format. Both are standard packaging options for through-hole resistors and do not affect component performance or compatibility.

Q: Which part should be selected for high-temperature applications?

A: The CMF5597K600FHEB supports operation to 175°C compared to 155°C for the RNF14FAD97K6, making it the preferred choice for elevated temperature environments.
